rlhis invention relates to mine cars and has for one object theprovision of a low height mine car of great lading capacity.

Another object of this invention is the o provision of a mine car havinga body supported by drop axles.

Still another object of this invention is the provision of a mine carhaving a body resting upon and supported by drop axles, the latter beingpositioned and retained by journal boxes and being free of directconnection with the body to permit the easy and quick separation of thebody and axles should occasion demand. R A further object of thisinvention is the provision of a mine car having a body supported on dropaxles, the body including a car bottom comprising a central floorportion and side floor portions, the central Hoor portion being arrangedabove the main portion of the axles but being positioned below thespindle portions of the axles whereby to provide for increased ladingcapacity, and the side ioor portions being so arranged as to intersectthe plane of the tops of the car wheels.

A still further object of this invention is the revision of a new andimproved mine car ody construction.

@ther objects and advantages of this invention will be apparent from thefollowing description taken in conjunction with the accompanyingdrawings in which:

Figure 1 is a longitudinal sectional view tlrough a portion of the carat one end thereo l Fig. 2 is a side elevation of the opposite end ofthe car, certain parts being shown in section and other parts beingshown broken away.1

Fig. 3 is an end view of the car at the gate end thereof.

Fig. 4f is a sectional view on the line H, lFig. 5 and 45 llig. 5 is afragmentary top plan view of the car; the view showing one end of thecar and a portion of the opposite end, certain parts of the car beingshown in section.

Referring now more particularly to the drawings in which similarcharacters of reference designate similar parts in the several views,the car of the present invention comprises a body indicated generally atA mountedon and supported by drop axles B, on the spmdles 2 of which thewheels 6 are mounted for rotation.

rllhe body A has a lower portion composed of a metal bottom 8 and sidesills 10 formed integral therewith, the side sills having outwardlydirected flanges 12 for supporting the side door portions 14:. As shownclearly in Fig. l the side oor portions are substantially horizontal andintersect the plane ot the tops of the wheels 6; said wheels projectingthrough openings formed in the side door portions and covered by wheelhoods 16 riveted to the side door portions and the danges 12 as shown at18. lf desired, the wheel hoods 16 may be of such form as to extend toand be riveted or otherwise connected to vertical side walls 20 whichare preferably formed integral with the side door portions 14 and whichextend vertically upward therefrom. For stiening the side walls, beads22 are formed along 'the upper edges thereof.

The car of. the present invention is designed or end dumping and henceis provided with a ixed end wall 24C at one end of the car body and anend gate 26 at the opposite end of the body pivoted `tor swinging .etmovement as shown at 28. Obviously within the spirit of the presentinvention, the body may be designed for rotary dumping purposes in whichevent the body may be provided with xed walls at each end thereof.

From the description thus far it can be seen that the body of thepresent invention includes a metal bottom which may be a single sheet ofmetal, or a plurality of sheets if desired, the side edges of said metalsheet being odset to define side Hoor supporting portions or anges 12,the osets forming the body side sills 10. lin the instance shown theo'sets each include upwardly extending diagonal portions 30 andvertically arranged portions 32 with which latter the anges 12 areformed; the offsets being formed integral with the bottom plateeliminating the necessity of using independent sill members such ascommercial channels, I-beams and the 100 like, and the diagonal portions30 providing for increased lading capacity of the body as will beobvious.

For stiflenin the body, ties 34 are provided intermed1ate the ends ofthe body, which extend along the under surfaces of the bottom and alongthe side sills 10 and side floor portions 14 and then upwardly along theside walls suitable fasteners such as rivets 36 being provided forsecuring the ties to the body. The ties may be, if desired,longitudinally ribbed or corrugated as shown at 38 (see Fig. 5) thoughthis is merely by way of example. For further stiflening the body,stifeners 39 are provided adjacent each end of the body which extendfrom the side sills 10 outwardly under the side floor portions and thenupwardly along the vertical side walls 20 (see Fig. 5).

At each end of the ca r an end sill is arranged, the same comprising a Zsection 40, the upper flange 42 of which is of substantial width andprojects outwardly from the end wall 24 and end gate 26, respectively.As shown clearly in Figs. l and 5 the opposite ends of the car bottom 8underlie the lower flanges 44 of the end sills and are secured theretoby suitable fasteners 46, the latter also serving, to secure underbumper plates 48 forming part of the end bumpers of the car. The bumperseach include a filler block 50 mounted on the plates 48 and providedwith a top bumper plate 52 riveted as at 54 to the web 56 of the endsill, the rivets 54 at one end of the car also serving to secure andfasten the before mentioned fixed end wall 24 to the adjacent end sillsas clearly shown in Fig. l. The bumpers each include a front plate 58which overlaps the top and bottom plates 52 and 48 respectively. rlheupper flange 42 of the respective end sills also serves as part of acoupling member to receive a coupling pin 60 which extends vtherethroughand through a coupling plate 62 and through the bumper, all as clearlyshown in Figure 1. For stiflening the end wall 24 spaced diaphragms 64are provided which are secured to said end wall and to the upper flange42 of the end sill.

As before mentioned the car of the present invention is designed for enddumping and to permit easy discharge of the lading` from the car body.an end slope sheet 66 is provided which is riveted to the car bottom 8and which extends upwardly from the bottom at an incline and its forwardedge substantially abuts the upper edge of the web 56 of the adjacentend sill and is welded thereto as shown at 68. The sheet 66 is of suchform as to nicely fit between the side sills 10 and the side edgesthereof are connected to said sills, preferably by welding, as shown at67. For providing additional support for the slope sheet 66, a diaphragm7() is secured to the bottom 8 and end sill by Jfasteners 72 and 73respectively; said diaphragm being arranged longitudinally of the bodyand having an upper supporting flange 7 5 upon which the slope sheet 66rests. If desired, openings may be formed in the slope sheet 66 topermit direct connection thereof with the flange 7 5 by Weld metal.

To stiften the car body at the junction of the side sills, end walls andbottom, corner angles 74 are provided which are attached to the body andend sills by suitable fasteners such as rivets 76. As before mentionedherein the body is supported on drop axles, but said body is not secureddirectly to said axles in order that the body and axles may be easilyseparated to permit replacement of parts. rlhe body is provided withaxle brackets 78 which are secured to the side sills and which embracethe trunnion portions 80 of the axles, thereby mounting the axles inwhat might be termed a floating manner relative to the car body. Theaxle brackets may be of any preferred or desired construction, but asshown in the drawings they include the attaching portion 82 whichconforms to the shape of the side sills to fit against thediagonal andvertical portions 30 and 32, respectively; said attaching portions beingslotted to permit removal and replacement of the axles therein. Adjacentthe slots in the attaching portions 82, the axle brackets are providedwith ribs 84 for stiffening purposes, which ribs extend upwardly to apoint such that lthey underlie the flanges 12 of the sills 10 and serveto stifl'en said flanges as will be apparent. For retaining the axles,retaining ins 86 are provided which are removably bsitioned betweenadjacent ribs 84 of each bracket.

From the above description it is believed that the construction of thecar of the present invention will be fully apparent to those skilled inthe art. It is to be noted that the car of the present invention is oflow height and yet provides for an extreme lading capacity. The car isalso devoid of independent elements such as channels, I-beams or Z-barsfor body sills inasmuch as the sill members are formed as integral partsof the bottom portion of the car body; said bottom portion being, ineffect, pan-shaped and com prising a metal bottom portion, the sideedges of which are oflsct to define the body sills, and the ofl'setportions provide supporting flanges for the side floor portions whichform a part of the upper portion of the car body. It will also beapparent that replacement of parts is easily and quickly effected byremoval of the pins 86 to permit removal of the body from the axles; thebody being free of direct attachment to the axles.
